Planning a beach trip this Memorial Day? Here’s one hidden danger you shouldn’t overlook
- Replies 0
As the long weekend approaches, many of us are eager to head to the coast for some well-deserved sunshine, ocean breezes, and perhaps a seafood meal or two.
But before you pack your beach chairs and flip-flops, health experts are sounding a quiet but urgent alarm about something you can’t see—but should definitely know about.
It’s not sharks or jellyfish that have officials concerned.
The real threat this summer is microscopic and potentially deadly.
Vibrio vulnificus is a bacteria found in warm coastal waters that can cause life-threatening infections, particularly for older adults or those with certain health conditions.
What is Vibrio vulnificus?
Vibrio vulnificus is a naturally occurring bacteria found in warm, brackish water—especially along the Gulf Coast.
It can enter the body through tiny skin openings, such as cuts or scrapes, or through the consumption of raw or undercooked shellfish, particularly oysters.
While the bacteria is invisible to the naked eye, the effects can be devastating.
Once inside the body, it can cause a severe infection known as necrotizing fasciitis, sometimes referred to as “flesh-eating disease.”
In extreme cases, it can lead to amputations—or even be fatal.

Why is this becoming a bigger issue?
Traditionally, Vibrio vulnificus was limited to warmer regions like Florida and Texas.
But as ocean temperatures rise due to climate change, its reach is spreading.
Infections have now been reported along the East Coast, the West Coast, and even in unexpected places like Alaska and Chile.
According to the CDC, the US sees around 80,000 cases of Vibrio infections each year.
Many go unreported or misdiagnosed, and experts believe the actual number could be higher.
On the East Coast alone, the number of wound infections has increased eightfold over the past 30 years.

How people get infected
There are two main routes of infection:
Real-life stories show the risk is serious
Unfortunately, there are heartbreaking examples.
In Texas, 66-year-old Randy Bunch died after a minor scrape on his foot became infected while fishing.
In California, Laura Barajas, a mother of one, lost all four limbs after contracting the bacteria from eating undercooked fish.
These aren’t rare cases.
Many others have shared stories of sudden swelling, intense pain, and serious illness—often within days of exposure.

These symptoms can worsen quickly, so seek medical attention right away. Early treatment with antibiotics can save lives.

Why older adults should be extra cautious
As we age, our skin becomes thinner, healing slows down, and immune systems may weaken.
If you have diabetes, liver disease, or take medications that suppress your immune system, it’s especially important to take these warnings seriously.
The ocean is still a wonderful place to relax and spend time with loved ones.
But staying informed about hidden risks like Vibrio vulnificus can help ensure that your beach trip is remembered for sunshine and laughter—not a hospital visit.

How people get infected
There are two main routes of infection:
- Through open wounds: Any small break in the skin—like a cut, scrape, or insect bite—can allow the bacteria to enter if exposed to contaminated water.
- By eating raw or undercooked seafood: Shellfish like oysters are a common culprit. Handling raw seafood with bare hands can also pose a risk if you have open skin.
Real-life stories show the risk is serious
Unfortunately, there are heartbreaking examples.
In Texas, 66-year-old Randy Bunch died after a minor scrape on his foot became infected while fishing.
In California, Laura Barajas, a mother of one, lost all four limbs after contracting the bacteria from eating undercooked fish.

Where are the hotspots?
- Gulf Coast: Florida sees the most reported cases, with popular beaches like Siesta Key and Tampa Bay listed in recent outbreaks. Texas, Louisiana, Mississippi, and Alabama are also common hotspots.
- East Coast: Cases have been reported in Virginia, the Carolinas, Maryland, and New Jersey.
- West Coast and Hawaii: Fewer cases, but infections have still occurred in California and Hawaii.
Symptoms to watch for
If you’ve been in coastal waters or eaten seafood recently, keep an eye out for:
- Redness or swelling near a wound
- Blistering or skin discoloration
- Fever, chills, or nausea
- Weakness or confusion
- Gastrointestinal distress (if ingested)
These symptoms can worsen quickly, so seek medical attention right away. Early treatment with antibiotics can save lives.
How to protect yourself
There’s no need to cancel your beach plans—but a few simple precautions can make all the difference:
- Wear protective footwear: Avoid going barefoot, especially if you have cuts or scrapes. Water shoes or boots offer better protection.
- Cover wounds: Use waterproof bandages to protect even minor skin openings.
- Be cautious after storms: Vibrio levels spike after hurricanes or flooding. Give water time to clear.
- Cook seafood thoroughly: Don’t eat raw oysters or undercooked fish. Always wash hands after handling seafood.
- Know your risk: Older adults and those with chronic conditions like diabetes or liver disease are more vulnerable.
